It has already been fixed and will be released in the next version which I believe is 4.0.4. I'm thinking 4.0.4 will be released to support subscribers so it will make the next GA release whichever and whenever that will be.

What is in svn currently?
I haven't had a chance to update it and build.

My email is attached to a premium support account even though my profile only says Sencha User.

No access for you! Currently they are working on the 4.0.4 branch in Git.. not sure how we are deploying to support subscribers since we don't do development in SVN anymore. I will see if I can change your title and permission here in the forum tho.

Yep working good thanks.
I sent you a pm from my usual forum name.
I'll clean up the menu.Menu for use with the hbox and set it in the feature request I just wanted to double check the issues I was hitting was confirmed in ext code and not something i introduced reason for the bug report.

Also I did some digging and issue #3 is if using css images instead of text the hbox layout defaults to the minWidth instead of calculating what the width would be from css. The hbox is only handling the positioning using left.
